Section 3: Purlin Installation
NOTE: The purlin will lay perpendicular to the rafters.
1) Start from the back of the pergola and place the
first purlin 5” from the 5” post. Space the
remaining purlins evenly.
2) The purlin overhang should be the same distance
from either side of the last rafter. It is helpful to
have an additional person to assist with adjusting
the purlin overhang.
3) Use the #10 x 1 ½” self-tapping screws and screw
caps to secure the purlin to the rafters. Do not over-tighten the screws as this
will cause dents in the purlin.
Section 4: Finish Work
1) Place the post caps on the posts. Secure with small beads of
vinyl glue.
2) Secure the finials onto the headers and rafters with vinyl
glue.
3) Glue the end caps on the purlin. Use a dab of glue to secure
the caps.
Enjoy your new pergola!
